Jens,What are you trying to achieve? From memory you can add multiples to the alarm (you can certainly add the DSC official serial board and the envisalink to the same panel). If it is a plug-in instance then I am guessing the same approach you can do for the Hue plugin would work to create a second instance if you have two alarms.Thanks,Neil

You can definitely have two registered on the keybus, it basically just acts as a keypad (and from memory you can have up to 8, assuming you have the power for it). I’ve got two envisalinks plus a IT-100... one envisalink for Homebridge-envisalink, one for indigo and the IT-100 also connected to indigo using a slightly modified version of the plugin (the envisalink used for things like zone bypass, the IT-100 for virtual keypad and triggers as I find it much faster and more reliable than the envisalink!
